Comparative Dynamics of Substorms and Sawtooth Events

Journal of Geophysical Research: Space Physics, Volume 131, Issue 6, June 2026.
Abstract We present a comprehensive comparative analysis of magnetospheric substorms and sawtooth events using multi‐point observations from ground‐based magnetometers, geostationary satellites, and the Time History of Events and Macroscale Interactions during Substorms mission.

A New Strategy for Improving Multi‐Frequency PPP‐RTK Ionospheric Correction Availability and User Performance in Low‐ and Middle‐Latitudes

Journal of Geophysical Research: Space Physics, Volume 131, Issue 6, June 2026.
Abstract High‐precision regional ionospheric correction products are essential for achieving accurate and fast‐convergence solutions in Precise Point Positioning Real‐Time Kinematic (PPP‐RTK). For users in low‐ and middle‐latitudes, PPP‐RTK server narrow‐lane (NL) ambiguity resolution (AR) typically requires more than 10 min, which largely affects the ...

Mastcam‐Z Spectrophotometric Properties of Materials at the Van Zyl Overlook, Jezero Crater

Journal of Geophysical Research: Planets, Volume 131, Issue 6, June 2026.
Abstract During Sols 63–65 of Mars 2020, Mastcam‐Z multispectral (442–1022 nm) images were acquired at Van Zyl Overlook (VZO), spanning phase angles from ∼0° to 150°, to model photometric parameters for seven surface units. These units included rocks, soils, regolith, and rover tracks near the Jezero landing site.

Martian Proton Albedo as Signature of Near‐Surface Water

Journal of Geophysical Research: Planets, Volume 131, Issue 6, June 2026.
Abstract Understanding the Martian soil water budget is crucial not only for in situ resource utilization in future human missions to Mars, but also for reconstructing the geological and climatic history of the planet, as well as to assess the potential of ancient or even present microbial life.

New High Precision Measurements of Apollo Samples: 0.3–5 GHz Complex Refractive Indices

Journal of Geophysical Research: Planets, Volume 131, Issue 6, June 2026.
Abstract Active and passive radar techniques provide information on the subsurface structure and history of planetary bodies. However, interpretations of radar data are limited by our understanding of the complex dielectric permittivity and magnetic permeability of the surface material.
